Over watering... the plant can't take up nutrients as well to support photosynthesis or that amount of light.kush autoflower i have 9 plants in4x4x7 tent this is the only plant showing this
is this light burn or something else i have 1 mars hydro tsl 2000 and 2 mars hydro ts1000 all daisey chained
plant is 4 weeks 2 days old
temps 74 to 83 day 68 to 74 night
planted in perlite and fox farm lights are about 36 inches above canopy was at 75 percent just now dimmed to about 69 percent
last feeding was 2 days ago 3/4 to 1 gallon of water ph was 6.6 ppm 328 i had mixed 5 gallons of water with 5 tsp of ff grow big and 3 tsp of big bloom

i did what you said with the fan . i just dont see how i keep overwatering i do what you guys say i water till runoff and when the pots are dry and weightless i water again always like 4 or 5 days goes by between wateringOver watering... the plant can't take up nutrients as well to support photosynthesis or that amount of light.
Move the fan to the floor make sure it on low and oscillating it will help dry the pots out increase transpiration and reduce the micro climates caused by the dense growth. Aka high humidity around the leaves.
Reduce your humidity is part of it also I feel but I can't be sure without numbers.
Ok then it's the humidity. I assume over watering because that's 99% of the time what the issue is. It's a transpiration issuei did what you said with the fan . i just dont see how i keep overwatering i do what you guys say i water till runoff and when the pots are dry and weightless i water again always like 4 or 5 days goes by between watering
Calcium is usually one of the first deficiencies to show when transpiration rates are low.I looked in my Ed Rosenthal book. It looks like the plant in the example on calcium deficiency. If your PH is too low you need to ad some calmag.
humidity stays between 58 and 63 most the time but there have been a few hours it was higher i have a 6 inch ac infinity fan with filter i have the 12 inch oscillating fan in that corner and directly across in the other corner is a 9 inch fanOk then it's the humidity.

See that swelling between the veins of the leaves. 99% of the time it's over watering. The other thing that will cause that is humidity and by that I mean the humidity right at the leaf on the bottom side. Your room maybe ok at like 50-60% but if it's high right around the leaf it reduces the transpiration to much.
What is your humidity at? And can you give some info on your air exchange?
Move the fans to the bottom... very slight breeze through the plants.. lower humidity to about 50%.humidity stays between 58 and 63 most the time but there have been a few hours it was higher i have a 6 inch ac infinity fan with filter i have the 12 inch oscillating fan in that corner and directly across in the other corner is a 9 inch fan
fans are on the floor now i will do my best to lower itMove the fans to the bottom... very slight breeze through the plants.. lower humidity to about 50%.
